eSonar is working to achieve this by:

  • Sponsoring targeted research to develop and test relevant new technologies.

  • Developing scientific and technological evidence to identify, model, predict and validate the most promising noise reduction technologies, designs and marine mammal detection systems.

  • Providing guidance to industry, academia and the International Maritime Organization to influence and develop vessel standards that will quickly lead to meaningful long-term noise reductions.


The features of the eSonar Marine Mammal detection system include:

  • Uses acoustic monitoring to detect underwater radiated noise from passing vessels in accordance with the American Bureau of Shipping’s (ABS) recommended measurement guidance.

  • Measures each passing vessel’s noise signature--when deployed in a fixed location near a shipping channel—and detects and records the presence of whales for a range of more than eight kilometres.

  • Alerts passing vessels of their noise signature and advises on the presence of whales detected in the vicinity, using the system’s built-in communications capabilities.

  • Provides calibrated ship-noise-only measurement that vessel owners can use as ABS qualified data to support low noise designation for their vessels. (This has the added benefit of significantly lowering related fees at an increasing number of ports.)

  • Portable, inexpensive, and easy to install and operate.

Marine Mammal Detection and Underwater Radiated Noise Management

Managing and reducing Underwater Radiated Noise to protect marine mammals is a primary concern for the marine industry worldwide. eSonar, in partnership with the American Bureau of Shipping and with Memorial University, is actively working to develop a comprehensive marine mammal detection system.


The aim of this partnership is to reduce the impact of commercial shipping activity on endangered marine mammals. eSonar’s objective is to speed the deployment of technologies that:

  • Reduce the impact of underwater radiated noise on marine species, and

  • Improve marine mammal detection by operating vessels so they can take action to reduce the risk of acoustical and physical disturbances on these marine species.
